SPECIFICATION forming part of Letters Patent No.491,292, dated February7, 1893.

Application filed October 24, 1892. fierial No. 449,812. (No model.)

To all ZUhONI/Zd may concern.-

Be it known that I, HENRY A. MATTHEWS, of Southbnry,in the county of NewHaven and State of Connecticut, have invented a new Improvement inStovedinobs; and I do hereby declare the following, when taken inconnection with accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in-

Figure l, a front view of a stove-knob constructed in accordance with myinvention. Fig. 2, a plan view thereof. Fig. 3, a view Fig. -l-, adetached front view of the flanged jewel. Fig. 5, a view showing all ofthe parts arranged in the order of their assemblance.

My invention relates to an improvement in stove-knobs, the object beingto produce a simple, cheap, ornamental and durable article.

With these ends in View, my invention consists in the combination with asheet-metal shell, of a flanged-ring applied to the open end thereof,and having its outer edge turned down upon the outer face thereof, and aflanged, glass jewel interposed between the said shell and ring, theinner edge of the latter engaging with its flange to retain it in place.

My invention further consists in certain details of construction as willbepointed out in the claims.

In carrying out my invention,I construct glass jewel A, having a smoothhemispherical contour, and provide it around its base with a flange a,which is engaged by the inner edge of a flanged ring 3, the outer edgewhereof is clasped over the open end of the sheet-metal shell 0, whichmay be of any ap proved construction. Preferably, and as herein shown, Iinterpose a disk 1), between the open end of the shell and the jewel forthe same to rest upon.

I am aware that knobs provided with jewels are not broadly new, butheretofore they have been secured in place by spinning or drawing metalover their edges, which is liable to break them, and which does not holdthem so securely as when they are flanged as provided for by myinvention. Of course the form of the jewel may be varied as desired, solong as the flange at its base is retained.

Havingfully described myinvention, What I claim as new and desire tosecure by Letters Patent is:

1. In a stove-knob, the combination with a sheet-metal shell, of aflanged ring applied over the open end, and having its outer edge turneddown upon the outer face, thereof; of a flanged glass jewel interposedbetween the said shell and ring, the inner edge of the latter engagingwith its flange and retaining it in place, substantially as described.

2. The combination with a sheet metal shell, of a disk applied to theopen end thereof, a flanged ring applied over the said end of the shell,and a flanged glass jewel interposed between said disk and ring,theinner edge of the said ring engaging with its flange to hold it inplace, substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
